The National Weather Service has issued a Winter Weather Advisory for 6 a.m. to 7 p.m. Saturday. They are calling for anywhere from 2-4 inches of snow across the region.

Here’s their forecast:Snow accumulations 2 to 4 inches, with a chance that rain could mix in across the far southern and eastern portions of the region, which would cut down on the accumulations.

Snow will spread over the region near daybreak in Northeastern Maryland and northern Delaware, then hit the I-95 corridor through the Philadelphia region by mid- to late-morning.

Motorists should expect snow-covered roadways and reduced visibility

Temperatures will be in the mid-30s.

A Winter Weather Advisory for snow means that periods of snow will likely cause trouble traveling. Motorists should expect snow-covered roads and limited visibility. Bridges and overpasses are likely to be slick.

The storm is developing in Texas and will track just south of our area Saturday. With cold air already in place, plus a southern track like that, it adds up to likely snow over much of our area.

But the storm is not expected to strengthen too much, or bring up enough moisture, to make it a major storm but it should still leave at least a couple of inches of snow on much of the region.

With temperatures below freezing, the snow will stick on untreated surfaces. The snow should continue through much of the day, keeping temperatures in the mid-30s at best.

The snow is expected to be heaviest between 9 a.m. and noon but should continue throughout the day. Some melting could occur when the snow gets lighter.

Most of the area is expected to get 2 to 4 inches of snow, and that includes the Philadelphia area, and even counties just south of there. Enough rain should mix in farther south to limit any accumulation.

The storm will move out Saturday evening, with increasing winds and colder air moving in for Sunday.
